Title: Improvements in valves for gas mains and the like
IPC: F16K3/20
Filed: 1928-12-31
Abstract: 331,261. Morrison, J. A. Dec. 31, 1928. Sluice valves; seats.-In a valve for shutting off the flow of blast furnace gas through a main, an apertured flat plate closure member is adapted to be lifted by a cable and winding gear 22 to bring the unperforated portion of the plate into position when it is desired to close the valve, the lifting of the plate being facilitated by a counterpoise weight. In either position the plate 1 is clamped between two seat - carrying members 9 which are attached at their opposite ends to the flanged ends of the mains by flexible rings 8. The seat-carrying members are secured to the pipesupporting structure by flexible extensions 16. The seatings are moved into or out of contact with the plate 1 by means of an operating gear 41 which causes two interconnected levers 32 to rotate eccentric pins 33 fitted to one seat member 9 and coupled through two links 30 and plain pins 31 to the other seat members. Rotation of the pins 33 causes the distance between the points of attachment of the links 30 to the seat members to be varied, the amount of separating movement being limited by nuts 37, 38 at the outer ends of bolts 36; the latter carry rollers 50 at their centres to act as guides for the edges of the valve plate.

Title: Abrasion resistant devices
IPC: B29C48/09
Filed: 1972-10-18
Abstract: 1417561 Coated products ATLAS CORP 18 Oct 1972 [14 June 1972] 38689/72 Heading B2E [Also in Divisions B5 and F2] An abrasion-resistant device e.g. a hose for use in aircraft comprises an inner member 21 having thereon an ablative covering 23 of flame protective material the material being a mixture of an elastomer base and a particulate filler and, when subjected to heating, undergoing separation of portions of the material from the surface of the covering. The base may be a silicone-type polymer or polyvinylidene fluoride and the filler a fluoroplastic material such as polytetrafluoroethylene, polychlorotrifluoroethylene or fluorinated ethylene - propylene polymer, the particle size being in the range of 0.001 inch to 0.015 inch or 0.005 to 0.075 inch diameter and the proportion of base to filler material being preferably in the range of 25 to 75% by weight. The covering may comprise different colour strata so that abrasion of one strata reveals the next or the material may include fluorescent or light reflective substance for detection of abrasion. The covering may be applied by direct extrusion by a screw thread extrusion head (Figs. 2, 3, not shown) or by wrapping a pre-extended strip around the tube. In the latter case the edges of the material may be stepped to provide for overlapping when wound around the tube (Figs. 5 and 6, not shown). Alternatively the covering may be applied by the extrusion apparatus shown in Fig. 9 in which a billet 55 of plastic is placed in cylinder 52 and is squeezed and caused to flow through the die 53 by a ram 54 so as to form a covering around the tube 21a. This is particularly suitable where a number of colour strata are to be applied the billet 55 then being composed of coloured layers which are reproduced in the covering on a reduced scale. A reinforcing braid 22, e.g. of stainless steel may be interposed between the tube 21 and the covering 23 and an electrically conductive layer may be incorporated or electrically conducting or radioactive material may be incorporated in the covering. A further jacket covering 24 of similar material to the first may be applied by extrusion or by heat shrinking a preformed jacket on to the first covering. This further jacket may also be suitably coloured. A further corrugated outer jacket 58 may also be applied. A clamp (Fig. 8, not shown) for securing hoses and using the covering material as a cushion is also disclosed.

IPC: G06F11/273
Filed: 1970-08-12
Abstract: 1,253,648. Digital electric calculators; fault detection. WESTERN ELECTRIC CO. Inc. 12 Aug., 1970, No. 38944/70. Heading G4A. A digital computer having a number of storage circuits, and a number of processing circuits interconnected by a number of data paths is provided with a maintenance arrangement which includes circuits for setting data into and reading data from the storage circuits via separate test signal paths independently of the normal data paths. General.-The computing system which is described in some detail is of modular configuration and is especially suited for real time operation, e.g. for controlling a petroleum processing plant. The programme store is duplicated, both stores being simultaneously accessed, the first to respond causing the request to the other to be cancelled. Instruction registers are provided for storing short programme loops which may be repeated without necessitating additional fetch operations from the programme stores. Maintenance and diagnostic systems.-These systems may be programme or manually controlled, a control panel having fault indicating lamps being provided for manual operation. Operation in the manual mode may be truly manual or semi-automatic where operator selected diagnostic programmes are called from, e.g. magnetic tape stores. The system also allows the operator to sequentially step through a programme and observe the displayed results at each step. Under programme control a sequencer sets data in and reads data from a selected storage circuit in the computer over a time shared data bus. A number of test sequences are stored which are selected by an accessing circuit. Address checking is performed during the tests in order to ensure that the correct circuit is under scrutiny. The diagnostic systems are connected to the circuits to be tested by duplicate channels to enable testing to continue in the event of a fault on one channel. Test data may be set into a selected circuit, read out from that unit, and compared with the originally transmitted data. Parity errors may be induced to test the efficiency of the system's parity checking circuits.

Filed: 1956-12-21
Abstract: 805,183. Feeding mechanism for stamping presses. PRESS AUTOMATION SYSTEMS, Inc. Dec. 21, 1956 [Dec. 27, 1955], No. 38988/56. Class 83 (4). A sheet metal handling apparatus for a press comprises a stationary casing element 16 suspended adjacent the press, a reciprocable gripper element 31 movable on guides on the casing element in a plane parallel to the working plane of the press, workpiece engaging means on said movable element and actuating means operatively interposed between the casing element and the movable element for effecting relative reciprocatory movement therebetween. The casing element is attached to a split clamp 23 which secures the apparatus to a mounting shaft 25. The reciprocable gripper element 31 moves on a slide shaft 30 supported in spaced hangers 28 from the upper flange 18 of the casing element and is guided by a block 40 depending from the lower flange of the casing member, said block being engaged by a pair pair of rollers 41 on the element 31 (Fig. 3). The lower flange 34 of the gripper element carries a longitudinally apertured block 45 accommodating an adjustable return cut-off cam 47 and also mountings 52 and 58 for an additional slide shaft 57 which carries a collar 58 movable along the shaft towards an end stop 59. The collar carries a pivoted gripping arm 62 having a gripper finger 64 at one end and a cam 63 at the other, which is engaged by a projection 66 on the stop 59 for closing the gripper finger against the gripper projection 66 on the stop for grasping a sheet metal blank. Reciprocation of the gripper element 31 is effected by a pneumatic cylinder unit 70 fixed to the casing element. The cylinder actuating rod 73 carries a pinion 76 meshing with racks 77 and 78 on the stationary casing elements and gripper element respectively. This arrangement enables the gripper element 31 to be displaced through a distance twice that of the actuating piston in the pneumatic cylinder and therefor gives a rapid stroke to the gripper element. A second actuating cylinder 80 supported on the slide shaft 57 actuates the grippers by means of a rod 82. Actuating fluid is supplied to the cylinders 70 and 80 from a supply 95 via a regulator valve 98 and a control valve 100 (Fig. 5). The control valve is automatically operated by an electrical control circuit fully described in the Specification and an arrangement of switches is incorporated in the control circuit for initiating each cycle of operation manually if desired. The handler may be supported independently of the press on stanchions displaced to either side of a conveyer or on a cantilever arm attached to the press. Alternatively, the handler 15 may be suspended over a conveyer C from an overhead arm 127 (Fig. 10), attached to the press P.

Filed: 1960-11-18
Abstract: 965,538. Ferroelectric devices. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 18, 1960 [Dec. 21, 1959], No. 39683/60. Heading H1K. [Also in Division H3] A temperature stabilizing circuit comprises a capacitor of ferroelectric material maintained in an ambient temperature which lies below the Curie temperature and an A.C. signal source connected across the capacitor to provide hysteresis heating so that the dielectric is at a stable temperature just below the Curie point. Fig. 2 shows a dielectric amplifier using a non- linear capacitor 10a with a crystal of tri-glycine sulphate as dielectric. Electrodes 14a and 16a of large areas are connected to A.C. generator 20a and the capacitor is mounted in an oven 18a so that the ambient temperature lies just below the Curie temperature. The currents from generator 20a then heats the crystal due to hysteresis effect and since the area of the hysteresis loop decreases with temperature, a stable equilibrium operating temperature for the crystal dielectric results. Two other electrodes 22 and 24 of smaller area are connected in series with coil 30 and load resistance 34, across signal generator 32, the stable operating temperature providing stable operating characteristics. D.C. bias to control the value of the capacity is provided by voltage source 36 and a switch 38 is provided to vary this bias and thus the capacitance between electrodes 22 and 24. In a modification, only one pair of electrodes is provided, the current from the signal generator being sufficient to produce the stabilizing hysteresis heating. The D.C. bias switch effectively provides an on-off modulator for gating A.C. signals or alternatively a controllable A.C. generator may replace the D.C. bias switch to provide modulated A.C. signals.
